Don't know what nutes your using but you may wanna use coco specific nutes. Coco usually needs more cal/mag and is more like hydro so your def gonna have to watch the ph. It's gonna dry out faster than soil so your gonna need to water/feed more. The best thing would've been to get some fox farm and just go from there. That way you wouldn't have to worry about adding nutes until sometime in flower. Hope it turns out for you bro

Yeah they're all right I forgot to mention about specific nutes and other info you might want to do a little research I'm usig coco perk on my grows and I use cal mag for every watering and on nutes. I have too water every 3 days sometimes two if the girls are hungry. I myself like to use coco it's just my choice but it's no for everyone. Its good to try new things as well until you find what suits you best.

Ppm meter is good but I don't think it's essential IMHO. I think pH is more important. If you start with low doses of feeding and watch to see how plants are doing then a ppm meter isn't really necessary. But this requires to be able to watch the plant more and see how it's doing

That depends entirely on medium.

For me in coco I find my EC aka ppm a vital part of the way I grow.

However though. I've found that if I keep my EC going in between 0.8 and 1.6 that I generally don't need to pH as it sits anywhere between 5.5-6.4. Which to me in coco is acceptable.

The higher my EC the lower my pH gets but unless I hit above 1.8EC it doesn't need adjusting other than when using a PK booster.

You are certainly correct about medium. It does depend on that. You know your setup and how your nutes work so you really don't have to pH since you tracking how much food you give them. IMHO you don't need ppm meter either cus when you grow your plants and as long as you don't go high on ec your pH will be in range so all you would have to do is just watch your plant and bump up nutes when it looks like she needs more. If you never go over 1.8 then your prolly using somewhere between 1/2 and 3/4 strength nutes so you would be fine without a meter IMHO

You are most likely correct about the meter for mixing my nutes.

But I like to track runoff EC too as I never plain water feed. I just constantly feed.

I completely understand bro. It all depends on the grower I suppose. What nutes are you using? Sounds like they have some great pay buffers in them

I use CANNA coco A/B, CANNA MONO Ca, CANNA MONO Mg, a little PK1314.

My tap water has an EC of 0.2 and a stable pH of 6.8.

In previous grows I've also used CANNA RHIZOTONIC and CANNAZYM.

Trying my next run without them to see if it makes any difference to my yields because if there is very little difference it will have saved me £43/$60

My average yield is around 400g from my 400w setup.

Sometimes more sometimes less. Haven't been able to break the 450g mark yet. Max was 439g.


I'm very much a simple kind of grower.

Plenty of training with a decent enough veg time and keep my leaves green, healthy and performing well.

My seedling is getting worst. I re-potted on coco (75%) and perlite (15%) and bring down my ph to 6.3. But there is no improve. The soil mix was to hot for her. So i'm starting to germinate another seed but i dont know if i should use coco with perlite.

Here are some photos.

Thank you all for your support!

If it's still getting worse then maybe something else must be going on with your grow. I notice yor grow room/tent do you have any other ventilation other than those fans like exhaust and intake?
 
It has 1 bathroom exaust (240m per hr) and two pc fans + those 2 fans too. Also an air hole on the top

That's dry strange I don't know what I can up with maybe you got unlucky with the seedling and had very poor genetics or you might be doing something wrong sorry but maybe someone else can help

You can make small changes to soil pH by applying soil amendments. However, you’ll have best success if you select plants that are adapted to your soil pH and other soil characteristics. Adding organic matter such as compost to the soil buffers the pH, which means that it tends to bring both acid and alkaline soils closer to neutral.
